TECHNICAL FIELD

Example embodiment of the present invention relates to an inclinationangle adjusting apparatus for adjusting an inclination angle of anantenna using a rotatory power, wherein a remote control unit is easilycombined with the inclination angle apparatus.

BACKGROUND ART

An antenna transmits or receives an electromagnetic wave by outputting acertain beam, and thus the antenna must be able to adjust direction ofthe beam. An apparatus of adjusting the direction of the beam is aninclination angle adjusting apparatus.

FIG. 1 is a perspective view illustrating a common first inclinationangle adjusting apparatus.

In FIG. 1, the first inclination angle adjusting apparatus 100 includesa power delivering member 102, a body 104 and a driving member 106.

In case that a user rotates the driving member 106 using his hand, thepower delivering member 102 moves linearly in response to the rotationof the driving member 106. As a result, a phase shifter (not shown)connected to the power delivering member 102 controls phase of a RFsignal inputted from an outside, thereby adjusting an inclination angleof the antenna. Here, a thread 108 is formed on the power deliveringmember 102, and a structure (not shown) corresponding to the thread 108is formed on an internal surface of the driving member 106 so that thepower delivering member 102 moves in response to operation of thedriving member 106.

In the above first inclination angle adjusting apparatus 100, thedriving member 106 may be moved by an external force such as quake,impact, etc despite a user does not rotate the driving member 106.Accordingly, to prevent this moving phenomenon, the first inclinationangle adjusting apparatus 100 fixes the driving member 106 using a cap110 when the inclination angle is not adjusted.

In case that the user wants to rotate the driving member 106 using aremote control unit such as a motor, etc, the cap 110 is separated fromthe driving member 106, and then the remote control unit is combinedwith the driving member 106. As a result, it is inconvenient to separatethe cap 110, and the separated cap 110 may be lost.

FIG. 2 is a perspective view illustrating a common second inclinationangle adjusting apparatus.

In FIG. 2, the second inclination angle adjusting apparatus 200 includesa power delivering member 202, a body 204 and a driving member 206.

The driving member 206 is combined with a thread 216 formed on an end ofthe power delivering member 202 so that the driving member 206 is fixedto the power delivering member 202. Here, the power delivering member202 moves linearly according as a user pushes or pulls the drivingmember 206, and a phase shifter connected to the power delivering member202 adjusts an inclination angle of the antenna in response to themoving.

The body 204 houses the power delivering member 202, thereby protectingthe power delivering member 202.

Power delivering member fixing members, i.e. a nut 208, a bush 210 and afixing member 212 fix the power delivering member 202 so that the powerdelivering member 202 is not separated from the body 204 by an externalforce such as quake, etc.

However, in case of controlling the second inclination angle adjustingapparatus 200 using a remote control unit, the power delivering memberfixing members and the driving member 206 must be separated before theremote control unit is combined with the power delivering member 202. Asa result, inconvenient process of combining or separating the powerdelivering member fixing members and the driving member 206 should beperformed. In addition, the separated members may be lost.

FIG. 3 is a perspective view illustrating an inclination angle adjustingapparatus in an antenna according to one example embodiment of thepresent invention.

In FIG. 3, the inclination angle adjusting apparatus 300 of the presentembodiment adjusts an inclination angle of the antenna, and is connectedto a phase shifter 316 as described below. Particularly, the inclinationangle adjusting apparatus 300 delivers a rotatory power to the phaseshifter. The phase shifter 316 changes phase of a RF signal inputtedfrom an outside device (not shown) in accordance with the deliveredrotatory power, thereby adjusting direction of a beam outputted from theantenna. This will be described in detail with reference to accompanyingdrawing.

The inclination angle adjusting apparatus 300 includes a powerdelivering member 302, a body 304, a driving member 306 and anindicating member 312.

The power delivering member 302 is connected to the phase shifter 316,and delivers the rotatory power generated by the driving member 306 tothe phase shifter 316. Here, connection of the power delivering member302 and the phase shifter 316 is not shown, but may be variouslymodified as long as the power delivering member 302 delivers therotatory power to the phase shifter.

The body 304 houses the power delivering member 302, thereby protectingthe power delivering member 302. A scale for indicating change degree ofthe inclination angle may be indicated on a part of the body 304,preferably a part corresponding to the indicating member 312.

The driving member 306 combines with the body 304 so that the drivingmember 306 is rotated on the body 304. That is, the driving member 306combines with the body 304 so that a user can rotate the driving member306 using his hands. In addition, a projection member combined with thepower delivering member 302 is formed on an internal surface of thedriving member 306 as described below. Accordingly, in case that theuser rotates the driving member 306, the rotatory power is generatedfrom the driving member 306. The generated rotatory power is deliveredto the power delivering member 302 through the projection member.

An inserting section 310 is formed on an outside surface of the drivingmember 306 as shown in FIG. 3.

In the above description, the user rotates directly the driving member306, but the driving member 306 may be rotated by a remote control unit,e.g. a motor. In this case, the remote control unit 314 rotates thedriving member 306 under the condition that the remote control unit isinserted into the inserting section 310 of the driving member 306.

In one example embodiment of the present invention, the insertingsection 310 of the driving member 306 may have polygon shape so that therotatory power of the remote control unit is more much delivered.

The driving member 306 has cylindrical shape as shown in FIG. 3. Here, asliding protection projection member 308 may be formed on an outsidesurface of the driving member 306 so that the user's hand does not slidewhen the user rotates the driving member 306 using his hand.

The indicating member 312 indicates change degree of the inclinationangle, and moves in response to the rotation of the driving member 306.In this case, a user detects change degree of the inclination angle byverifying location of the indicating member 312 through scale indicatedat the body 304. In one example embodiment of the present invention, afirst thread is formed on a part of the power delivering member 302 asshown in FIG. 3 and FIG. 8, and a second thread corresponding to thefirst thread is formed on an internal surface of the indicating member312.

In brief, the inclination angle adjusting apparatus 300 of the presentembodiment generates the rotatory power by rotating the driving member306, and adjusts the inclination angle of the antenna using thegenerated rotatory power. Specially, the remote control unit is directlycombined with the driving member 306 by inserted into the insertingsection 310 without removing some of elements in the inclination angleadjusting apparatus 300. Hence, the inclination angle adjustingapparatus 300 of the present invention may more easily combine theremote control unit with the driving member 306 or separate the remotecontrol unit from the driving member 306 than the inclination angleadjusting apparatus in related art.

In addition, since no element is removed when the remote control unit iscombined with the driving member 306, the elements in the inclinationangle adjusting apparatus 300 of the present invention may be not lostunlike in the inclination angle adjusting apparatus in related art.

Hereinafter, the phase shifter combined with the inclination angleadjusting apparatus 300 and for changing phase of corresponding signalwill be described.

FIG. 4 is a top view illustrating a phase shifter according to oneexample embodiment of the present invention. FIG. 5 is a perspectiveview illustrating a lower part of the phase shifter in FIG. 4. FIG. 6 isa sectional view illustrating schematically the phase shifter in FIG. 4.

In FIG. 4 and FIG. 5, the phase shifter of the present embodimentincludes a dielectric substrate 400, a first line 402, a second line404, an input line 406, an output line 408, a rotation axis member 410,an arm member 412, a guide member 414, a first rotation member 500 and asecond rotation member 502.

The rotation members 500 and 502 located in a lower part of the phaseshifter are combined with the members 400, 412 and 414 located in anupper part of the phase shifter as shown in FIG. 6.

Hereinafter, operation of the elements in the phase shifter will bedescribed in detail.

The dielectric substrate 400 is made up of dielectric material having acertain dielectric constant. Here, a ground plate (not shown) is formedon a lower surface of the dielectric substrate 400 or in the dielectricsubstrate 400.

The first line 402 is a conductor, and is formed on the dielectricsubstrate 400 with for example curve shape. Here, ends of the first line402 are electrically connected to some of radiation devices (not shown),e.g. a first radiation device and a second radiation device, which isnot shown.

The second line 404 is a conductor, and is formed on the dielectricsubstrate 400 with for example curve shape. Here, ends of the first line402 are electrically connected to some of the radiation devices, e.g. athird radiation device and a fourth radiation device, which is notshown.

The input line 406 is a conductor. Here, a RF signal is inputted to theinput line 406.

Some of the inputted RF signal is outputted to a corresponding radiationdevice through a first dielectric substrate area located below theoutput line 408 without change of its phase. The other RF signal iscoupled at the rotation axis member 410, and then is outputted tocorresponding radiation devices through a second dielectric substratearea located below the arm member 412. As a result, an array antennahaving the radiation devices radiates a given beam which is changed inresponse to phase change of the RF signal in accordance withtransmission path of the RF signal.

The second rotation member 502 combines with the power delivering member302 of the inclination angle adjusting apparatus 300, and rotates inresponse to the rotatory power delivered from the power deliveringmember 302.

The first rotation member 500 rotates in response to the rotation of thesecond rotation member 502. In one example embodiment of the presentinvention, the second rotation member 502 is a gear worm, and the firstrotation member 500 is a gear wheel.

The rotation axis member 410 is connected to the first rotation member500 located in the lower part of the phase shifter, and is connected tothe arm member 412 and the guide member 414 located in the upper part ofthe phase shifter.

The rotation axis member 410 rotates in accordance with the rotation ofthe rotation members 500 and 502, and so the arm member 412 and theguide member 414 rotate in response to the rotation of the rotation axismember 410.

The guide member 414 is connected to the rotation axis member 410 andthe arm member 412 as shown in FIG. 6, and delivers the rotatory powerin accordance with the rotation of the rotation axis member 410 to thearm member 412. As a result, the arm member 412 rotates with guidemember 414 in accordance with the delivered rotatory power.

In brief, the phase shifter is connected to the inclination angleadjusting apparatus 300, and controls the phase of the inputted RFsignal in response to the rotatory power delivered from the inclinationangle adjusting apparatus 300. As a result, direction of the beamoutputted from the antenna is adjusted. That is, the inclination angleadjusting apparatus 300 provides the rotatory power to the phaseshifter, thereby adjusting the inclination angle of the antenna.

The phase shifter of the present embodiment may be variously modified aslong as the phase shifter uses the rotatory power delivered from theinclination angle adjusting apparatus 300, i.e. is not limited asstructure in FIG. 4 to FIG. 6.

Hereinafter, structure of the inclination angle adjusting apparatus 300will be described in detail with reference to accompanying drawings.

FIG. 7 is a perspective view illustrating the inclination angleadjusting apparatus in FIG. 3.

As shown in FIG. 7, a cylindrical home 700 and at least one imperfectcylindrical home 702 are formed on the body 304.

In case that the driving member 306 is combined with the cylindricalhome 700 as shown in FIG. 3, the driving member 306 may rotate on thecylindrical home 700 due to characteristic of the cylindrical home 700.However, in case that the driving member 306 is combined with theimperfect cylindrical home 702 as shown in FIG. 7, the driving member306 is fixed to the imperfect cylindrical home 702 without rotated.

In one example embodiment, at least one hook member is formed on theinternal surface of the driving member 306, which is not shown. In thiscase, the hook member is hung at the imperfect cylindrical home 702, andso the driving member 306 is fixed to the body 304. As a result, thedriving member 306 may be stably fixed to the body 304 though anexternal force such as impact, etc is generated.

In other words, a user combines the driving member 306 with thecylindrical home 700, and then rotates the driving member 306, therebyadjusting the inclination angle of the antenna. Subsequently, the userpulls the driving member 306 and combines the driving member 306 withthe imperfect cylindrical home 702, thereby fixing the driving member306 to the imperfect cylindrical home 702 so that the driving member 306is not rotated by the external force. In case that the user wants toadjust again the inclination angle of the antenna, the user pushes thedriving member 306 so that the driving member 306 is located on thecylindrical home 700.

In short, unlike the inclination angle adjusting apparatus in relatedart where the driving member is fixed by using extra members, theinclination angle adjusting apparatus 300 of the present embodimentfixes the driving member 306 through a simple method of pulling orpushing the driving member 306. Accordingly, extra member for fixing thedriving member 306 is not needed in the inclination angle adjustingapparatus 300.

FIG. 8 is a perspective view illustrating an inclination angle adjustingapparatus according to one example embodiment of the present invention.

In FIG. 8, the inclination angle adjusting apparatus 300 of the presentembodiment includes fixing members 802, 804 and 806 as well as the powerdelivering member 302, the body 304 and the driving member 306.

A projection member 800 is formed on an internal surface of the drivingmember 306 as shown in FIG. 8. An inserting section 808 is formed on anend of the power delivering member 302, wherein the projection member800 is inserted into the inserting section 808. That is, the drivingmember 306 is combined with the power delivering member 302 by insertingthe projection member 800 into the inserting section 808 when theinclination angle adjusting apparatus 300 is assembling.

In one example embodiment of the present invention, the projectionmember 800 has polygon shape so that the rotatory power generated by thedriving member 306 is more delivered to the power delivering member 302.The inserting section 808 has also shape corresponding to the projectionmember 800, i.e. polygon shape.

The fixing member 802 combines with a thread 810 formed on an end of thebody 304. Accordingly, in case that the driving member 306 is combinedwith the imperfect cylindrical home 702, the driving member 306 is notseparated from the imperfect cylindrical home 702 by the fixing member802 though the external force is generated. In other words, the fixingmember 802 fixes the driving member 306, and thus structurecorresponding to the thread 810 is formed on an internal surface thefixing member 802.

The fixing members 804 and 806 are combined with thread 812 formed on anoutside surface of the power delivering member 302 so that theindicating member 312, etc is not separated by the external force.

As described above, the inclination angle adjusting apparatus 300 of thepresent embodiment rotates the driving member 306, thereby rotating thepower delivering member 302. In other words, unlike the inclinationangle adjusting apparatus in related art which moves linearly inaccordance with operation of the driving member, the power deliveringmember 302 rotates in accordance with operation of the driving member306 in the inclination angle adjusting apparatus 300 of the presentinvention. Here, the phase shifter operates in response to the rotationof the power delivering member 302 as mentioned above.

Additionally, the inserting section 310 is formed on the outside surfaceof the driving member 306, wherein the remote control unit is insertedinto the inserting section 310. Hence, the inclination angle adjustingapparatus 300 of the present embodiment may combine the remote controlunit with the driving member 306 without removal of certain members.Accordingly, the inclination angle adjusting apparatus 300 of thepresent invention may combine (separate) more easily with (from) theremote control unit than the inclination angle adjusting apparatus inrelated art.

In one example embodiment of the present invention, in case that theremote control unit is inserted into the inserting section 310 under thecondition that the driving member 306 is fixed to the imperfectcylindrical home 702, the driving member 306 may be automaticallyseparated from the imperfect cylindrical home 702 and then be combinedwith the cylindrical home 700.

FIG. 9 is a perspective view illustrating internal structure of aninclination angle adjusting apparatus according to one exampleembodiment of the present invention.

As shown in FIG. 9, at least one projecting member 308 is formed on thedriving member 306 so that the user's hand does not slide. In addition,the projection member 800 for combining the driving member 306 with thepower delivering member 302 is formed on an internal surface of thedriving member 306. Here, shape of the projection member 800 may bevariously modified. It is desirable that the projection member 800 haspolygon shape so as to more deliver the rotatory power generated by thedriving member 306 to the power delivering member 302.

At least one hook member 900 is formed on an end of the driving member306 as shown in FIG. 9. The hook member 900 is combined with thecylindrical home 700 or the imperfect cylindrical home 702 of the body304.

In one example embodiment of the present invention, number of theimperfect cylindrical homes 702 is greater than that of the hook members900. For example, the imperfect cylindrical homes 702 has twice numberthan the hook members 900. This is because the hook members 900 combinemore rapidly and easily with the imperfect cylindrical homes 702 as thenumber of the imperfect cylindrical homes 702 is increased.

In brief, the inclination angle adjusting apparatus 300 of the presentembodiment combines the driving member 306 with the power deliveringmember 302 using the projection member 800, and fixes the driving member306 to the body 304 using the hook member 900 and the homes 700 and 702.As a result, the inclination angle adjusting apparatus 300 may delivermore the rotatory power generated by the driving member 306 to the powerdelivering member 302, and fix the driving member 306 to the body 304through the above simple method. Accordingly, the user may controleasily the inclination angle adjusting apparatus 300.
